Impact

Helen Blau is a stem cell biologist at Stanford University, where she has directed the Baxter Laboratory for Stem Cell Biology since 2000. Her laboratory studies cellular reprogramming, muscle stem cell function in regeneration, and strategies to rejuvenate aged cells and tissues. A central line of her recent work concerns 15-hydroxyprostaglandin dehydrogenase (15-PGDH), a prostaglandin E2-degrading enzyme her group identified as elevated in aged tissues, including skeletal muscle, and describes as a 'gerozyme'. Inhibiting 15-PGDH has been reported to improve muscle strength in aged mice, regenerate articular cartilage and reduce osteoarthritis-associated pain (Science, 2025), and support muscle repair during GLP-1 receptor agonist-induced weight loss (PNAS, 2026). She has also written on therapeutic approaches to sarcopenia (Nature Reviews Drug Discovery, 2026). Earlier work developed protein-interaction reporter assays, reflected in a series of patents. Blau is a member of the US National Academy of Sciences, the National Academy of Medicine and the Royal Society, received the US National Medal of Science in 2025, and served on the National Advisory Council of the National Institute on Aging (1996-2000). For longevity research, her work connects stem cell biology with drug targets for age-related muscle and joint decline.
